Corrugated boxes are the most widely used packaging products, and their usage has always been the first among all packaging products. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products, which are beneficial to the environment and easy to load and unload and transport.

[0003] For example, Chinese patent CN219172967U discloses a high-strength pressure-resistant corrugated paper box, including a box body, the upper end face of the box body is rotatably connected to four box covers, the inner side walls of the box body are fixedly connected to a first support plate in the middle, and the four diagonal parts inside the box body are fixedly connected to a second support plate, the upper end faces and lower end faces of multiple first support plates are each provided with a first card slot, the front end faces of multiple second support plates are each provided with a second card slot, and multiple M-shaped support bodies are fixedly arranged inside the box body and the four box covers.

[0004] The above-mentioned high-strength pressure-resistant corrugated paper box still has certain shortcomings. The first support plate and the second support plate are connected by the first card slot and the second card slot, so that the box body can support the pressure caused by external objects. However, it lacks support in the vertical direction. When it is subjected to vertical pressure, the corrugated paper box is easily damaged, which reduces the practicality of the high-strength pressure-resistant corrugated paper box.

[0031] In this embodiment, a carton base is fixed to the lower surface of the corrugated carton body 1. The shape of the corrugated carton body 1 is a rectangular body with a hollow interior and a missing upper surface. The base can be used to increase the height of the compression-resistant corrugated carton to prevent the bottom of the compression-resistant corrugated carton from getting damp.

[0032] See also Figure 3-4 In order to improve the compression resistance of the compression-resistant corrugated paper box, the compression-resistant mechanism 2 in this embodiment includes a side compression-resistant component and a vertical compression-resistant component. The side compression-resistant component includes four horizontal plates 201, four inclined plates 204 and eight slide plates 203. The four horizontal plates 201 are respectively fixed to the left and right side walls and the front and rear side walls of the inner cavity of the corrugated paper box body 1. The four mutually fixed horizontal plates 201 can improve the side support of the compression-resistant corrugated paper box. The eight slide plates 203 are divided into four groups. The four groups of slide plates 203 are respectively located below the four horizontal plates 201, and the four inclined plates 204 are respectively fixed between two adjacent slide plates 203.

[0033] In this embodiment, the vertical compression-resistant component includes eight vertical plates 202, and the eight vertical plates 202 are divided into four groups. The four groups of vertical plates 202 are respectively fixed on the lower surfaces of four horizontal plates 201. T-shaped grooves 205 are opened on the opposite sides of the eight vertical plates 202. The eight vertical plates 202 can improve the vertical compression resistance of the compression-resistant corrugated paper box. The eight slide plates 203 are respectively slidably connected to the inside of the eight T-shaped grooves 205. Two adjacent horizontal plates 201 are fixedly connected to each other. The four horizontal plates 201 are shaped as square frames. The eight slide plates 203 are respectively inserted into the inside of the eight T-shaped grooves 205 and moved to the bottom of the compression-resistant corrugated paper box. The four inclined plates 204 are respectively formed into triangles with the adjacent vertical plates 202, which can improve the lateral compression resistance of the bottom of the compression-resistant corrugated paper box.

[0034] It should be noted that the use of four mutually fixed horizontal plates 201 can improve the lateral support of the compression-resistant corrugated cardboard box, while the eight vertical plates 202 can improve the vertical compression resistance of the compression-resistant corrugated cardboard box. The four inclined plates 204 form triangles with the adjacent vertical plates 202, which can improve the lateral compression resistance of the bottom of the compression-resistant corrugated cardboard box. The base can be used to increase the height of the compression-resistant corrugated cardboard box to prevent the bottom of the compression-resistant corrugated cardboard box from getting damp.

[0035] See also Figure 5In order to make the compression-resistant corrugated paper box have waterproof and other properties, the waterproof component 4 in this embodiment includes a waterproof layer 401, a water-blocking layer 402 and a wear-resistant layer 403. The waterproof layer 401 is coated on the outside of the corrugated paper box body 1, the water-blocking layer 402 is fixed on the outside of the corrugated paper box body 1, and the wear-resistant layer 403 is fixed on the outside of the corrugated paper box body 1.

After the polyurethane waterproof coating is applied, the polyurethane waterproof coating will solidify into a film, which has strong adhesion and can resist pressure penetration. It can be used on the surface of various materials and is used to play a waterproof role. The water-blocking layer 402 is a polyvinyl chloride layer. The polyvinyl chloride layer of the water-blocking layer 402 has stable physical and chemical properties and is insoluble in water, alcohol, gasoline, gas and water vapor. It has low permeability. It can withstand any concentration of hydrochloric acid, sulfuric acid below 90%, nitric acid about 50% and caustic soda solution below 20% at room temperature. It has a certain chemical corrosion resistance, so it plays an anti-corrosion role during the transportation of the pressure-resistant corrugated paper box. The wear-resistant layer 403 is a polyethylene layer. The polyethylene layer of the wear-resistant layer 403 has good chemical stability and can resist the erosion of most acids and alkalis. It is insoluble in general solvents at room temperature, has low water absorption, excellent electrical insulation and high wear resistance, which can improve the wear resistance of the pressure-resistant corrugated paper box.

[0040] (1) The four mutually fixed horizontal plates 201 can improve the lateral support of the compression-resistant corrugated paper box, and the eight vertical plates 202 can improve the vertical compression resistance of the compression-resistant corrugated paper box. The eight slide plates 203 are respectively inserted into the eight T-shaped grooves 205 and moved toward the bottom of the compression-resistant corrugated paper box. The four inclined plates 204 are respectively connected to the adjacent vertical plates 202 to form a triangle, which can improve the lateral compression resistance of the bottom of the compression-resistant corrugated paper box. The base can be used to increase the height of the compression-resistant corrugated paper box to prevent the bottom of the compression-resistant corrugated paper box from getting wet.

[0041] (2) The waterproof layer 401 bonded to the outside of the compression-resistant corrugated paper box is composed of a polyurethane waterproof coating layer. After the polyurethane waterproof coating is applied, the polyurethane waterproof coating will solidify into a film, which has the characteristics of strong bonding force and resistance to pressure penetration, and can be used on the surface of various materials. At the same time, the water-blocking layer 402 is composed of a polyvinyl chloride layer. Polyvinyl chloride has stable physical and chemical properties and is insoluble in water, alcohol, gasoline, gas and water vapor. It has low permeability. At room temperature, it can withstand any concentration of hydrochloric acid, sulfuric acid below 90%, nitric acid about 50% and caustic soda solution below 20%. It has a certain chemical corrosion resistance, so it plays an anti-corrosion role during the transportation of the compression-resistant corrugated paper box. The wear-resistant layer 403 is composed of a polyethylene layer. It has good chemical stability and can resist the corrosion of most acids and alkalis. It is insoluble in general solvents at room temperature, has low water absorption, excellent electrical insulation and high wear resistance, which can improve the wear resistance of the compression-resistant corrugated paper box.
